making espressoFor coffee lovers nothing can be more exciting than making espresso at home with your new espresso coffee machine.  Espresso is a concentrated coffee beverage.  It is brewed by forcing hot water through finely ground coffee at a high pressure.

Espresso has a thicker consistency than other coffee brews, with a characteristic crema or foam on top.

The pressurized brewing process used in espresso machines produces a brew with a very high concentration of dissolved solids and flavors.  This makes espresso the perfect base for other coffee beverages such as lattes, mochas, cappuccino, macchiato, and americanos.

To make the best espresso at home with your new espresso coffee machine, you must start with very finely ground coffee.  Producing a shot of espresso is often called “pulling” a shot.  When you do this on your espresso coffee machine, a steady stream of brewed espresso coffee should come out evenly, with a light and creamy froth floating on top.  A single shot of espresso is 30 milliliters while a double shot is 60mL.

You will need about 2 teaspoons of ground espresso for a single shot, or between 7 and 10 grams.  A double shot requires between 12 and 18 grams or about 4 teaspoons.  Pour the ground coffee into the espresso filter basket.

Use a metal tamper to tamp the espresso into a dense puck.  The ground espresso should lie flat across the filter basket.

Attach the filter basket to your espresso machine and lock it in place.  Position a small espresso cup or demitasse underneath the filter basket.

Press the button for a “short pull” or a “long pull.”  The “short pull” button produces a very thick, syrupy espresso with stronger flavor.  The “long pull” button puts more water and the espresso produced is not as dense.

When the brewing process starts, hot water at 92°-96°C is forced through the ground coffee under a pressure of 9 bars.  If the water is too cool the espresso will taste sour.  If it’s too hot, the coffee will be bitter.  To make a good cup of espresso at home, your new espresso coffee machine should be able to maintain the water temperature within 1 or 2 degrees of the ideal temperature.

During the brewing process the oils and flavors in the ground coffee are extracted and emulsified.  This produces a thick, rich beverage.  It usually takes 25 to 30 seconds for the water to pass through the ground coffee puck and into the receiving cup.  Making the best espresso at home with your new espresso coffee machine requires the right fineness of the ground coffee, tamping, and maintaining the ideal pressure and temperature of the water.

To savor your demitasse of espresso at its best, serve immediately and drink as soon as possible.  As an alternative, you can use the espresso to prepare cappuccino, lattes, macchiato or americanos.

Get the Best Out of Your Espresso Coffee Beans

Espresso coffee is the most concentrated form of brewed coffee.  Many people enjoy a shot or two of this beverage everyday.  Others use espresso as the starting point for a variety of coffee drinks such as lattes, cappuccino, mochas and americanos.  The perfect espresso starts with the best espresso coffee beans.

Start with quality coffee beans for espresso.  If you shop around you will find different types and blends of espresso beans that you can use.  Coffee beans from the Arabica plant are rich in flavor and aroma.  They are often blended with Robusta coffee beans for a full-bodied espresso.  Robusta beans lack flavor and aroma but have a higher concentration of caffeine than Arabica.

For espresso coffee, dark medium roast to very dark roast is typically used. When purchasing roasted coffee, take a close look at the beans.  The darker roasts should have an oily and shiny look but not charcoal black.  If properly roasted, darker beans should produce coffee that is slightly sweeter.

Darker roasts burn off some of the caffeine and acid and caramelizes the natural sugars in the coffee bean.  Lighter roasts, on the other hand, produce coffee that is acidic, bitter, and less sweet.  Most people prefer darker roasts for espresso coffee beans.  This produces espresso that is relatively sweet and with less bitter aftertaste.

For great tasting espresso at home, it is best to use freshly ground espresso coffee beans.  The beans must be very finely ground, almost like a powder.  If you are looking for a coffee grinder for home use, there are two types to choose from.

One type of coffee grinder uses cutting blades to chop the coffee beans at high speed.  This type of grinder is relatively cheaper in price.  This type of grinder, however, does not produce uniformly ground coffee.  In addition, the heat generated in the grinding process produces a bitter taste in the coffee.

The burr grinder uses two grinding elements to slowly crush the coffee beans without heating up the beans.  This type of grinder is more expensive but produces a uniform grind.  You can get superior ground coffee for espresso, French press, or drip coffee maker.

Finally, a good espresso coffee machine combined with the right technique will produce a richer and fuller beverage for you to enjoy.  The proper technique involves tamping the ground beans just enough.  Your espresso coffee machine must also be able to maintain the ideal temperature and pressure of the water through the coffee grounds.  All of these components are necessary if you want great-tasting espresso coffee everyday.
